I'm having a bit of trouble with an m-file in matlab, i posted earlier but i appreciate that post was too vague for a response.

basically i have an m-file which goes like this

function [y]=logmap(lam, x)

%calculate population size, y, next year using:

%lam: effective growth rate of population (between 0-4)

x: current size of population

using the logistic mapping formula

y=lam*x*(1-x)

but what I really need is for it to loop, so that y goes back in to it as the x value and then just keeps repeating it.

does anyone know the commands to make it do this, the "for" and "while" loops don't seem to have the right inputs for the situation, also i need to define a value, n, which is the amount of times i want it to loop.

can someone please give me a hand?

thanks
